Case file LinkedIn Crossclimb #867: 4-letter ladder, 5 middle exhibits, combo prompt "Two synonyms of the word "variety."". Endpoints: SORT (top) and KIND (bottom).
Middle phase answers: "Aching a bit, as after a run" = SORE; "Opposite of less" = MORE; "Swampy land" = MIRE; "Dig in the earth for precious metals" = MINE; "“Make up your ___” (come to a decision)" = MIND.
Ordering phase: the valid middle chain is SORE → MORE → MIRE → MINE → MIND. This permutation is the only valid one-letter chain for these answers.
Evidence link: SORT → SORE. T→E at the fourth letter (SORT → SORE).
Evidence link: SORE → MORE. S→M at the first letter (SORE → MORE).
Evidence link: MORE → MIRE. O→I at the second letter (MORE → MIRE).
Evidence link: MIRE → MINE. R→N at the third letter (MIRE → MINE).
Evidence link: MINE → MIND. E→D at the fourth letter (MINE → MIND).
Evidence link: MIND → KIND. M→K at the first letter (MIND → KIND).
Verdict: SORT → SORE → MORE → MIRE → MINE → MIND → KIND satisfies every one-letter constraint. The combo clue "Two synonyms of the word "variety."" describes both end words together — "SORT" and "KIND" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
